Referring in detail designates. a service station-in the form ofapparatus for vending oil, gas and water to motorists, and for likepurposes. Said stato the drawings, 10 I tion comprises a metal casing 11secured to the grooved or other suitable base 12, at its lower ed eportion 13. Said casing comprises a ront ,wall 14, side walls 15,\16.and a top wall 17. The latter wall may be rounded or otherwise suitablyshaped for ornamental purposes. Mounted on'said top wall 17 is lamp 18of any'suitable attractive construction for illuminating or advertisingpurpose. At the lower rear portion thereof, said casing is formedf-withan-extension 19 having an opening 20. A door 21 hinged at its upper edge22 may be locked to said casing as by lock 23 shown in Fig 2.

In the front face 14 of saidv casing are a number of slots for receivingcoins for controlling the operation of the dispensing devices. The kindof liquid dispensed and the character of the coins to be inserted are indicated by suitable markings adjacent the respective slots. Thus at theleft of 'said front wall, a slot 25 may be marked Oil. and 1 Quarter.Secured to said front wall 14 below said slot, and extending rearwardlyfrom said wall is an elongated horizontal sleeve 26 of rectangularcross-section. A coin guide member 27 communicating with slot 25 leadsdown to said sleeve 26 which is provided with a slot 28 forpermittingthe coin deposited in said slot 25 to drop into said sleeve.

Mounted within said sleeve 26 is a rack 29 having gear teeth 30 formedat the lower edge thereof. An elongated plate 31 is slidably mountedwithin said sleeve 26 in par allel relation to said rack 29. Integrallyformed with said plate 31 is an elongated stem or rod 32 extendingwithin said sleeve and thru a slot 33 formed in the front wall 14 of thecasing. Said rod 32 terminates in a handle member 34 for reciprocatingsaid plate 31 within said sleeve 26. An upstanding arm portion 35integrally formed with Said plate 31 at one end thereof, is adapted. toride in slot 36 formed in the upper wall 37 of sleeve 26 and serves tolimit the movement of said plate 31 in both directions. A projection 38fixed to the inner face of said plate 31 extends between said plate andrack 29. A pair of spaced projections 39 intogrally formed with saidrack 29 extend in- Wardly from the inner face thereof, substantially inalignment with said projection 38. Extending beneath said plate 31 whichis of less height than the sleeve 26, is a wall 40 slidably supportingthe plate 31. It will now, be understood that a. coin 41 inserted thruslot 25 and passing downwardly thru guide 27 and slot 28 will drop onsaid wall 40 and between the projections 38 and 39. Should this occur, apulling force on the handle 34 will cause sliding movement of both plate31 and rack 29 since these members are interlocked by the coin 4'1abutting the projections 38 and 39. Should the coin. 41

be smaller than the space between the upper and lower projections 39.the projection 38 will merely push said coin thru said space and therack 29 will hence not be moved by pulling the handle 34. Extendingbeneath said sleeve member 26 is a. coin guide ,inined quantity of oilwhen a proper coin has been inserted inslot '25 and the rack bar movedas described above. To this end,'a gear 45 is rotatably mounted on shaft46, a one-way roller clutch 47 being interposed between said gear andsaidshaftQ Fixed to said shaft 46 is a plate 48 adapted to be rotatedonly when the rack 29 is being moved forward toward wall 14., Returnmovement of the rack will only rotate gear 45 without affecting eithershaft 46 or the plate 48. Said return movement of the rack 29 iseffected by a coil tension spring 49 fixed on its bottom end 50 in anysuitable manner within the easing and connected to the rear end 51 ofplate 31 as by a belt 52 rolling over a pulley 53. A pin and slotconnection 54 between the plate 31 and rack bar 29 is adapted to returnsaid rack bar to the position shown in Fig. 6 when said plate is movedto the right under the influence of tension spring 49.. The relativesizes of the gear 45 and rack 29 is such that a single forward stroke ofthe plate 31 will cause complete revolution of said plate 48. Mounted ona bottom supporting plate 55 fixed within the casing 11 adjacent edgeportion 13 is a cylinder 56,- disposed directly beneath said plate 48.Within said cylinder is a piston 61 having a piston rod 62 extendingthru a suitable opening 63 in the top wall 64 of said cylinder. Aconnecting rod 65 pivotally connects said piston rod 62 and an ec entricpin fixed to plate 48 as at 66 and 67 respectively. Mounted within thecasing 11 as on plate 55 is an oil. barrel 68 supported within saidcasing 11. in a slightly inclined position as shown in Fig. 1 of thedrawings. interconnecting the barrel 68 and the bottom of the cylinder56 is a short pipe 69 having a one-way check valve 70 interposed thereinfor a purpose hereinafter appearing.

The front wall 14 of casing 11 is provided with an opening 71. Mountedon the inner surface of said front wall adjacent the lower edge of saidopening is a trough member 72 having a bottom wall 73. Flow-off or drippipe 74 interconnects the bottom of said trough with the top portion ofthe barrel 68. Mounted on said bottom wall 73 is a container 75 adaptedto be inserted thru the'opening 71 of front wall 14. A handle member 76may he provided for manipulating said container 75.

A retrieving mechanism 77 is provided for drawing said container 75 backinto its position as shown in Fig. 6 when said container has beenwithdrawn from said/opening and released after use. Said retrievingmechanism 77 comprises a drum 77a rotatably mounted on a shaft 78, saidshaft and drum being interconnected by a spiral spring 79. A chain 80 isadapted to wind on the outer surface of said drum and interconnects thelatter with the container 75. A pipe 81 connected to the bottom of thecylinder 56 extends upwardly and terminates in a downwardly curvedportion 81a disposed directly above the container 75. A one-way checkclear. The purchaser need merely insert a coin in slot 25 forinterlocking plate 31 and rack member 29. If the coin is too large, it

will not enter the slot 25.' If it is too small it will not interlockwith said members 29 and 31. If the coin is of the proper denomination,said members will be interlocked and the plate 48 given a completerevolution. This movement of plate 48 will cause the piston 61 toreciprocate vertically in the cylinder 56.

. On the upstroke of the piston, oil will be rack 29 to the normalposition.

drawn in from the barrel 68 thru pipe 69 and check valve 70 and, on thedown stroke, the oil will be forced out thru check valve 82,-

Said register is preferably mounted on the front wall 14 directly abovethe sleeve 26, and may be provided with'a pivoted arm 86, the endportion 87 of said arm extending in, the path of an upstandingprojecting "87a" formed with rack 29. Upon movement of said rackforpumping oil-, the arm 86 will I thereby be movedfor actuating theregister. A spring 88 is adapted to return the arm86 to its originalposition upon return of the Said register may be further provided with adisc 89 adapted to rotate progressively as the arm 86 is actuated.Saiddisc 89 is formed .with

peripheral notch 90. Pivotally mounted on a fixed shaft 91 is a bellcrank 92 having an arm 93 maintained in contact with the periphery ofdisc 89 as by a light spring 94. The upper portion 95 of said bell crankis adaptedto support a plate 96 which slidably extends within the'sleeve 97 fixed to the .front face of wall 14 above slot 25. When thedisc 89 hasbeen rotated a complete revolution, by a predetermined numberof oscillations of arm 86, the end portion 93 of the bell crank 92 willenter the notch under the influence of spring 94. This movement willdisengage the upper end of said bell crank from the plate which isthereby permitted to drop behind the slot 25 forobstructing the same.Further deposit of coins will not thereafter be possible until propreadjustment of the parts. The register 85 may be so adjusted that theplate 96 is caused to obstruct the slot 25 when the oilbarrel 68 issubstantially empty.

The service station 10 is further provided with means for dispensinggasoline. To said end, a gasoline tank 100'is preferably embedded in theground beneath the casing 11 in the usual manner. Said tank is connectedto an ordinary gasoline hand pump 101 by a pipe 102. A crank handle 103extending beyond said casingis fixed to a shaft 104 rotatably mountedwithin the casin and extending thru said wall 16 thereof: Fixed on saidshaft 104 are spaced gears 1 05 and 106 which mesh with a pair ofvertical racks 105a and 106a interconnected by a cross bar 107. Saidracks extend into the pump 101 and are adapted when moved upwardly byrotation of handle 103- in the proper direc-. tion to pump gasoline thruthepipe 108 and a hose 109 mounted in a manner hereinafter described. vI

A coin control mechanism is provided for permitting the purchaser topump predetermined quantities of gasoline. Forthis purpose the frontwall 14 in the casing is provided with two coin slots 110, 111. One ofsaid slots 110 may be marked Half dollar and the other slot 111 may bemarked 2 Dimes. Extending inwardly from said wall 14 below said slots110, 111 are horizontal sleeve members 110a and 111a respectively. Coinchutes 110?), and 1116 provide passages for coins from said slotsto theinterior of sleeves 110a, and 111a respectively. Slidably mounted withinsaid sleeves 110a, 111a are plates 112, 113, respectively. Said plates112, 113-are provided with stems 112a, and 113a respectively, extendingthi'u openings 112b and 1136 in a front wall 14 and terminating in heads1120, 1130. Said plates 112, and 1.13 are formed with vertical slots114, respectively'on the inner faces thereof. Slot 114 is adapted toreceive the half dollar de posited into slot 110. Should a coin of asmaller denomination be inserted in slot 110,

said coin being thinner than the half dollar will drop thru a slot 116formed in the bottom wall 117 in sleeve 110a. Slot 115 in plate 113is'adapted to receive the dimes in serted thru-slot 111. The height ofthe plate 113 is equal to the height of the two dimes as clearly shownin Fig. 3. Tension springs 116a secured to the rear end portions 112d,113d ofsaidplates 112 and 113are adapted to normallyretain saidplates-in retracted position as shown in Figs. 3 and 5. Rotatablymounted on a shaft 117 a journaled in bearing brackets 118 fixed to wall14 are a air 1 20. Lever 119 is provided with an arm 119a having anofi-set portion 1196 and an extension 1190 projegting into the lowerportion of slot 114. Likewise, lever 120 is provided with an arm 120ahaving an off-set portion 120?) and an extension 1200 projecting intothe upper portionof slot 115. It will now be of substantiallysymmetrical levers 119,

understood that upon insertion of the proper coin into-chute 1106, thecoin dropping into slot :114 will be interposed between the end ortion112d and plate 112, said extension 1190 of the lever 119.- When the halfdollar I Thus, should. a smaller coin be inserted in "126 at its lowerend slot 110, the coin would not be retained within said slot 114 bysaid projections 121, but would fall thru slot 116. Likewise, when thetwo dimes. are inserted in slot 111 and said dimes are lodged withinslot 115, one above the other, the upper one of said dimes is interposedbetween the extension 1200 of lever 120 and the end portion 113d ofplate 113. A pulling force on head 1130 will hence cause pivotalmovement of the lever 120. The lower dime may be supported by a pair ofspaced projections 122 formed at the inner surface of said-plate 113.Obviously, if only one dime is inserted into the slot 111, said dimewould be ineffective to interlock the plate 113 and the lever 120. Uponout-ward movement of either of plates 112, 113 the coins are broughtinto alignment with the coin chutes 124 and 125 respectively'whence thecoins are conveyed to the coin deposit box 44.

Means are provided for preventing operation of the pump 101 until theproper coins have been deposited in slots 110, and 111, and forpreventing the purchaser from pumping more than a predetermined quantityof gasoline, corresponding to the coins deposited.

, Attached to lever 1.19 adjacent the off-set portion 119?) thereof, isa depending integral arm 126 ext-ending below said sleeve members 110a,111a. Pivotally attached to said arm portion 127 as by a pin and slotconnection 128, is a horizontal slidably mounted member 129. The lattercom-- prises a bar 130 mounted on a pair-of fixed aligned guides 131disposed on either side of the shaft 104. Formed with said bar 130 are apair of symmetrically spaced horizontal U-shaped members 131, 132, andslidably mounted within member 131 is a plunger 133 having a pin andslot connection 134 with said member. A coil compression spring 135interposed between the rear end of said plunger and wall 136 of saidmember 131 normally maintains said plunger in extended position, asshown in Fig.3. Attached to the cross bar 107 which interconnects theracks 105a, 106a is a vertical depending member 137 disposed inalignment with said U- shaped members 131 and provided with one wayratchet teeth 138 adapted to engage a tooth portion 139 formed at oneend of plunger 133.

Thus when the parts are in the position illustrated in Fig. 3, turningmovement of the handle 103 for pumping gasoline is prevented since theracks 105a, 106a connected to the pump mechanism within pump 101', cannomove upwardly due to the locking lnteren gagcment of teeth 138, 139.However, when the lever 119 is rotated in clockwise directlon as seen inFig. 3, the bar 130 is translated to the left for releasing member 137.Said member 137 is further provided with oneway ratchet teeth 140disposed in a direction opposite to teeth 138. A plunger 141 slidablymounted in U-shaped member 132 1n a manner similar to the mounting forplunger 133 is provided with a tooth 142 and adapted to interlock withsaid teeth 140 of member 137 upon movement of the bar 139 to the left.Such movement of course, takes place when the lever 11.94 is rotated inclockwise direction topermit actuation of the pump for dlspensing thegasoline. Thus, actuation of the pump handle in a direction for movingthe racks 105a, 106a downwardly is prevented while the bar 130 is movedto the left. As will hereinafter be pointed out, said bar 130 will beautomatically moved to the right only when the full and proper amount-ofliquld has been pumped.

Attached to the upper ends of levers 119, 120 as by a pin and slotconnection 150, 151 are a pair of stop members 152, 153 for limiting theupward movement of ratchet member 137 and consequently the actuation ofthe pump 101 for dispensing the gasoline. Said stop member 152 comprisesa horizontal arm 154, an upstanding vertical arm 155 extending from oneend of said arm 154,, and a horizontal arm 156 extending from the upperend of said arm 155. Said arm 154 1s slidably received in, the guidemember 157, whereas the arm 156 is slidably received in a guide member158; Actuation of the lever 119 will thus cause reciprocation of saidmember 152. The stop member 153 comprises a horizontal arm 159, adepending vertical arm 160 and a horizontal arm 161 extending from thelower end of said arm 160. Arm 159 of said member 153 is likewiseslidably received in the guide member 157, whereas thearm 161 isslidably received in a guide member 162 simila r to and spaced directlybelow said guide member 158. Said arm 154 of member 152 is provided witha slot 163- wherein is received at the right end thereof as shown inFig. 3, a pin 164 fixed to the inner surface of arm 159. It will now beunderstood that rotation of lever 119 will move member 152 to the rightwithout moving member 153. However, upon rotating the lever 120, bothmembers 153 and 152 will be moved to the right since pin 164 Which isfixed to arm 159 contacts a portion of arm 154 at the end of slot- 163.Thus, lever 119 is rotated in a counterclockwise direction uponactuation of either plate 112 or 113.

The arm 156 is provided with a ramped member -158 is a ball 16.8normally pressed against upper surface of said arm l56.by spring 169.Formed in the upper surface of said arm 156 is a notch 170 adapted toreceive the lower portion of said bell 168 upon movement of saidmember152 to the right, for retaining said member against accidental movement.A tension spring 171 fixed at one end 172 thereof, attached to saidmember 152 at its opposite end, normally tends to move said member 152to the left. Arm 161 is, likewise provided with a ramped portion 165aand notch 170a for receiving a spring pressed ball 168a.

Upon insertion of a half dollar in slot 110, the coin drops thru chute110?) into slot 114, thus interlocking the extension 1190 of lever 119with plate 112. The plate may then be pulled outwardly for rotatinglever 119 in a clockwise direction. Such rotation will release plunger133 from engagement with the ratchet member 137 and will simultaneouslymove member 152 to the right, bringing the ramped portion 165 andextension 166 directly above cross member 107. This movement will alsocause the spring pressed plunger 141 to abut teeth-140 of said ratchethandle 133 may then be rotated for pumping liquid but not in a reversedirection. During such pumping action, the gears 105, 106 meshing withrack 105a, 106a, will move the cross member 107 upwardly. This movement,which is now permitted since the plunger 133 is retracted, may thencontinue until said cross membermember. The pump 107 strlkes the rampedportion 165 of member 152. Upon contact with said ramped portion 165,the member 152 will be caused to slide slightly and to the left causingthe ball 168 to be lifted from the notch 170 and thus permitting thespring 171 to move the member 152 to the left, and thereby rotatinglever 119 in a counterclockwise direction to again bring plunger 133into contact with ratchet 137. Further pumping is thereafter prevented,and the pump handle must be rotated in the opposite direction to againlower the ratchet member 137 before any pumping action may again takeplace. Upon" insertion of 2 dimes in slot 111, the same aption takesplace except that and120 are rotated simultaneously (due to the pin andslot connection 163, 164) Thus the'lower arm 161 is brought intoalignment above with the bar 107 and only the lesser uantity of liquidcan 'then be pumped. QlVhen the bar 107 strikes the ramped portion 165aof the arm 161, a similar unseati'rrg action ofthe spring pressed 'ball167axtakes place to permit return movement of member 153 under theinfluence ofj'tension spring 171a. At the end, such return movement ofmember 153, the pin 164 moving in the slot' 163 in arm .154 strikes saidarm for unseating ball 168 to permit retraction of memboth levers 119her 152 by spring 171. It will be notedthat the purchaser will not beable to rotate the handle 103 for lowering the bar 107 until said barstrikes either arm 161 or'156.

The hose 109 for receiving gasoline is wound on a drum 175provided witha retrieving spring 176. Thus, before starting the pumping operation,drawn by pulling the nozzle 177 and inserting the tip of said nozzlewithin the propergas tank opening. Said nozzle is provided with a smallbell crank 17 8 which is movable by pin ing the hook end 17 8a of saidbell crank to engage the undersurface of the gas tank adjace'nt themouth while the gas is being pumped. The 'nozzle is thus rigidlysuppkprted in themouth of the gas tank while t e After the full quantityof liquid hasbeen pumped, pin 179 may be pushed downwardly for releasingthe bell crank 178. Upon being released, the nozzle may then be drawnback to the casing since spring 17 6 will then wind the hose 109 on thedrum I7 5.

Coin control means is provided for vending water. To this end, the frontwall 14 of the casing 11 isprovided with a slot 180 marked \Vat er.Below said slot may be designated the coin to be inserted as forinstance 1 Nickel. Secured to said wall 14 is a coin chute 181 forguiding the coin deposited in said slot. A bell crank 182 pivotallymounted beneath the outlet opening 183 of said chute is provided with anarm 1'84 adapted to receive thecoin 185 as shown in Fig. 8. Said bellcrank is provided with a second arm 186 adapted to contact the rearportion of said coin. Attached to said front wall 14 is a tubular member187 having an opening 188 in the end wall 193 thereof. Slidably mountedwithin said tubular member and extending thru said opening 188 and anopening 190 in said front wall, is a plunger 189 having a fixed collar191 extending within said tubular Infill?! 187. A coil compressionspring 192 in erposed between the hose is with- 179 connected theretofor causpurchaser is operating the handle 103.

iiially presses said collar against the rear surface of said front wall14. Said plunger is further provided with a portion 194 extending beyondsaid wall 14 and having a head 195. It will now be obvious that uponpushing the plunger 189 inwardly against the pressure of the spring 192,the force is trans.- mitted thru the coin 185, thus causing clockwiserotation of the bell crank 182. v The coin thereafter drops into anysuitable receptacle. If no coin has been inserted in the slot 180, theinward movement of the plunger will not affect the bell crank. Mounted.

drum 198.- Said drum peripheral helical groove is provided 199 for thecwith a 1 water hose 200. The inner end 201 of said hose is connected to,a valve 202, which may be connectedthru a pipe 203 to any suitablewater-supply under pressure. Pivotally attached to said valve 202 is anactuating member 204, the mechanism being such that rotation of saidmember 204 in a counterclockwise direction will open the valve to permltflow of water from the hose. A spiral spring 205 normally maintains thehose in wound condition on the drum, the nozzle 206 of said hose beingnormally drawn against the front wall 14 of the casing. Arm 184 of thebell crank 182 is provided with a detent 207 adapted to engage withinthe groove 208 formed in a tubular portion 209 adjacent the nozzle ofthe hose. Thus the hose cannot be drawn out while the detent 207 extendswithin the groove 208. However, upon the insertion of a proper coin inslot 180, rotation of the bell crank 182 may be effected for lifting thedetent and for permitting with-- drawal of the hose.

Means is provided for automatically pivoting the actuating member 204fromthe normally valve closing position shown in Fig. 8 upon drawing thehose out to start the flow of water. To this end, an .end wall 210 ofthe drum 198 is provided with a spiral groove 211. A pin 212 fixed to ablock 213 slidably mounted on the actuating member 204 extends into saidgroove 211. Upon drawing the hose from the casing, the drum 198 rotatesand the pin 212 moves. inwardly towards the center of the drum becauseof the spiral groove 211. When said pin'212 contacts the portion of thewall 210 on the inner end of the spiral groove, as designated by numeral214, further outward movement of the hose will rotate said actuating arm204 for opening the valve 202. The nozzle 206 obviously may be insertedin the automobile radiator opening. After use of the water, release ofthe hose will permit the retrieving. spring 205 to rewind the hose andclose thewater valve and bring the parts to their original position.

Although the oil and gasoline pumps shown herein are hand operated, itis understood that electric motors or the like means may be provided foractuating said pumps.

It will thus be seen that there is provided a deyice in which theseveral objects of this invention are achieved, and which is welladapted to meet the conditions of practical use. r

As various possible embodiments might be made of the above invention,and as various changes might'be made in the embodiment set forth, it isto be understood that all matter herein set forth or shown in theaccompanying drawings is to be interpreted as illustrative and not in alimiting sense.
